to his Arabian Nights) mentions a precisely similar instrument as in use in China.  Somewhat similar is the “Chinese hedgehog,” a wreath of fine, soft feathers with the quills solidly fastened by silver wire to a ring of the same metal, which is slipped over the glans.  In South America the Araucanians of Argentina use a little horsehair brush fastened around the penis; one of these is in the museum at La Plata; it is said the custom may have been borrowed from the Patagonians; these instruments, called geskels, are made by the women and the workmanship is very delicate. (Lehmann-Nitsche, Zeitschrift fuer Ethnologie, 1900, ht. 6, p. 491.) It is noteworthy that a somewhat similar tuft of horsehair is also worn in Borneo.  (Breitenstein, 21 Jahre in India, 1899, pt. i, p. 227.) Most of the accounts state that the women attach great importance to the gratification afforded by such instruments.  In Borneo a modest woman symbolically indicates to her lover the exact length of the ampallang she would prefer by leaving at a particular spot a cigarette of that length.  Miklucho-Macleay considers that these instruments were invented by women.  Brooke Low remarks that “no woman once habituated to its use will ever dream of permitting her bedfellow to discontinue the practice of wearing it,” and Stevens states that at one time no woman would marry a man who was not furnished with such an apparatus.  It may be added that a very similar appliance may be found in European countries (especially Germany) in the use of a condom furnished with irregularities, or a frill, in order to increase the woman’s excitement.  It is not impossible to find evidence that, in European countries, even in the absence of such instruments, the craving which they gratify still exists in women.  Thus, Mauriac tells of a patient with vegetations on the glans who delayed treatment because his mistress liked him so best (art.  “Vegetations,” Dictionnaire de Medecine et Chirurgie pratique).

It may seem that such impulses and such devices to gratify them are altogether unnatural.  This is not so.  They have a zooelogical basis and in many animals are embodied in the anatomical structure.  Many rodents, ruminants, and some of the carnivora show natural developments of the penis closely resembling some of those artificially adopted by man.  Thus the guinea-pigs possess two horny styles attached to the penis, while the glans of the penis is covered with sharp spines.  Some of the Caviidae also have two sharp, horny saws at the side of the penis.  The cat, the rhinoceros, the tapir, and other animals possess projecting structures on the penis, and some species of ruminants, such as the sheep, the giraffe, and many antelopes, have, attached to the penis, long filiform processes through which the urethra passes.  (F.H.A.  Marshall, The Physiology of Reproduction, pp. 246-248.)
